I was team brad at the Defcon password cracking contest. I won 1st place in the street division. I used my own software (word machine) along with John the Ripper. No fancy, high-priced GPUs and no proprietary, closed-source software. There were 13 registered street teams.

Software I used Summary of hardware used
  • Intel(R) Celeron(R) CPU 430 @1.80GHz
  • Intel(R) Atom(TM) CPU N270 @ 1.60GHz ("GenuineIntel" 686-class) 1.60 GHz
  • Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz
  • AMD Phenom II 1090T
Passwords I cracked Final Notes
  • Thanks to KoreLogic for hosting the contest. You guys did a great job.
  • Special thanks to Solar Designer and john-devs. You guys write awesome software.
  • This is my last year of password cracking. I've made a case for pattern based password cracking. It works.
